In fact, V2 tackles this issue at efi_init() for both arm64 and risc-v.

Since in Zhen Lei's series "[PATCH v17 00/10] support reserving
crashkernel above 4G on arm64 kdump", [8/10] is self-standing and
meaningful. I abstract and utilize it.

I make a small change in it in order to use
early_init_dt_check_for_usable_mem_range() outside of/fdt.
(Cc: Zhen, please let me know if it is not fine for you.)

So finally these two patches can be applied as candidates for
Fixes: b261dba2fdb2 ("arm64: kdump: Remove custom linux,usable-memory-range handling")

v1 -> v2:
  Adopt Rob's suggestion to call
early_init_dt_check_for_usable_mem_range() from efi_init()
